Fund Class C: Fund Class C can be purchased or redeemed from fund management companies or sales organizations at any time. Different investment strategies Fund A: Since Fund A cannot be redeemed at any time, all the funds raised can be used for investment, so that fund management companies can formulate long-term investment strategies and achieve long-term business performance. Fund Class C: Fund Class C must reserve some cash for investors to redeem at any time, but it cannot be used for long-term investment, and generally invests in assets with strong liquidity.
